federation [ZONES...] {
NAME DOMAIN
upstream [ADDRESS...]
}
~~~
* Each **NAME** and **DOMAIN** defines federation membership. One entry for each. A duplicate
**NAME** will silently overwrite any previous value.
* `upstream` [**ADDRESS**...] defines the upstream resolvers used for resolving the `CNAME` target
produced by this plugin. If no **ADDRESS** is given, CoreDNS
will resolve External Services against itself. **ADDRESS** can be an IP, an IP:port, or a path
to a file structured like resolv.conf.
